1. A mobile device comprising: a drive element; a first battery configured to supply power to the drive element, a voltage of the first battery in a fully charged state being lower than a first voltage for driving the drive element; a stopping unit stopping supplying of power from the first battery when a voltage of an attachable/detachable second battery configured to supply power to the drive element is greater than or equal to the first voltage for driving the drive element; a node shared by a first path which supplies power from the first battery to the drive element and a second path which supplies power from the second battery to the drive element, the stopping unit including a booster unit provided on the first path and configured to switch between whether or not to boost a voltage of the first battery, and a diode provided on the first path and having electrical characteristics to prevent a current from flowing into the booster unit, an anode of the diode being electrically coupled to the booster unit and a cathode of the diode being electrically coupled to the node, the stopping unit allowing supplying of power from the first battery to the drive element via the diode in response to a voltage at the anode of the diode being greater than a voltage at the cathode of the diode, and the stopping unit stopping supplying of power from the first battery to the drive element in response to the voltage at the anode of the diode being less than the voltage at the cathode of the diode.
A mobile device includes a drive element and a primary battery that supplies power to the drive element. The primary battery's fully charged voltage is lower than the required voltage to drive the element. The device also has a secondary battery that can be attached or detached and supplies power to the drive element when its voltage meets or exceeds the required drive voltage. A shared node connects both power supply paths from the primary and secondary batteries. The device includes a stopping unit that controls power flow from the primary battery. This unit has a booster on the primary battery's path that can switch between boosting or not boosting the primary battery's voltage. A diode is also present on this path, preventing current from flowing into the booster. The diode's anode connects to the booster, and its cathode connects to the shared node. When the anode voltage exceeds the cathode voltage, power flows from the primary battery to the drive element. If the anode voltage is lower, the diode blocks current, stopping power supply from the primary battery. This ensures the secondary battery takes priority when its voltage is sufficient, optimizing power management.
2. The mobile device according to claim 1 , wherein the booster unit stops boosting the voltage of the first battery when the voltage of the second battery is greater than or equal to the first voltage and boosts the voltage of the first battery to a voltage greater than or equal to the first voltage when the voltage of the second battery is less than the first voltage.
A mobile device includes a first battery and a second battery, along with a booster unit that regulates the voltage between them. The booster unit monitors the voltage of the second battery and adjusts the voltage of the first battery accordingly. When the second battery's voltage is at or above a predefined first voltage level, the booster unit stops boosting the first battery's voltage. Conversely, if the second battery's voltage falls below the first voltage, the booster unit boosts the first battery's voltage to at least the first voltage level. This ensures that the second battery maintains sufficient power for critical operations while the first battery provides additional power when needed. The system dynamically balances power distribution between the two batteries to optimize performance and efficiency, particularly in scenarios where the second battery is prioritized for essential functions. The booster unit's control logic prevents over-discharging of the second battery while ensuring the first battery supplements power when required. This approach is useful in devices where one battery is designated for primary or critical functions, and the other provides supplementary power.
